I received an email from Heroku that deployment of some of my apps has failed (because of release phase failure) so I went to check and saw that these apps no longer have db attached to them. They simply removed it and I lost all data.
I understand that they announced few months ago that they are discontinuing their free plan for PostgreSQL. However, I didn't expect them to completely remove my database.
Some of these apps are paid apps. I'm paying $14/mo for web and worker dynos. Heroku's Mini PostgreSQL tier costs $5/mo.
I'd at least hope that they would shut down the database, but allow me to download a backup of my data.
